Double Exposure - Size Difference Between Skylab (SL)-1 and SL-2 - KSC

S73-25654 (7 May 1973) --- A deliberate double exposure to help illustrate the comparative sizes and configurations of the Skylab 1 and Skylab 2 space vehicles at Launch Complex 39, Kennedy Space Center, Florida. The double exposure creates an illusion that the rockets are side by side, though actually they are one and a half miles apart. The Skylab 1/ Saturn 1B space vehicle on Pad A is on the left. On the right is the Skylab 2/ Saturn 1B space vehicle on Pad B. The Skylab 1 payload is the space station cluster. The Skylab 2 payload will be an Apollo Command/Service Module (CSM) with astronauts Charles Conrad Jr., Joseph P. Kerwin and Paul J. Weitz aboard. The Saturn V launch vehicle is composed of a Saturn V first (S-1C) stage, a Saturn V second (S-11) stage, and the Skylab payload. The Saturn 1B launch vehicle consists of a Saturn 1B first (S-1B) stage, a Saturn 1B second (S-1VB) stage, and the CSM payload including its launch escape system. Photo credit: NASA
